93 to infinity

[brianburke]

Hi guys. I'm wondering what numbers I should use to tell Houdini "infinity". For example, in a max() function I want to make a number dip as low as possible but never to zero, what number should I use. On the other end, what should I use to set the maxdist of a ray tracing function to the maximum possible? I tend to just put a bunch of zeros or a bunch of nines, but surely there's something more correct to put?

Thanks!

Just a guess, I believe that Vex is based on C, so I did a quick search for the maximum and minimum that C can store in floats. This is what I found:

Hope it helps!

I'm pretty sure that for maxdist in ray-tracing functions, if you set it to -1, mantra will choose the maximum distance for you.

Otherwise, use the defines in limits.h (the single precision limits would be suitable I think)

Hey cool, this is perfect. Thanks!
